I received my second ever order yesterday. Reading about the vapor production I had ordered some VG juice along with some VG/PG juice to give it a try. I have only used PG juice up to this point and I knew that there would be some differences. The VG juice is supposed to be apple flavor. When I opened the bottle it sure didn't smell like apples - it smelled bad - almost like burnt toast but not sweet smelling, very acrid. I thought what the hell, maybe it tastes better than it smells. I filled a new cartridge and put it in a clean atty. With the first draw I knew something was really wrong - my mouth felt coated and slimy and so did my lungs - the taste was like satan pooped in my mouth - there was no apple flavor at all. I took another but it was worse. I had to wash everything out - the smell began to make me nauseous. Can VG juice go bad? The VG/PG juice seems to be okay and I have not had this problem with the PG juice I have. Or is it the flavor gone bad? So now I'm wondering - do I contact the supplier and let him know about this? Or do I just chalk this up to experience and get stuck with 2 bottles of this stuff? I am so disappointed - I so wanted to try the apple flavor so so badly. Please let me know your thoughts on this.
